Duct tape is great, as long as you don't accidently buy the insulated kind. I sure made a mess with that, it's a bit more sticky, and the stickiness stays on your quilt, I'm very careful now. I like my T-pins to pin the backing to the floor. I wish I had a wall big enough to spray baste on. I'm sure it would be my favorite tool. I do use it to baste my small projects, and absolutely love it. Otherwise, my favorite tool is my Janome 6500. She just does everything I ask her to, without narry a complaint. Worst investment was also one of those basting guns.
